screen or grid A. This screen is su ported by a frame which is preferably meta lic and which serves to provide necessary rigidity to ho1d the screen taut and to permit handllng and moving ofthe device as a whole.

In the form illustrated in Figures Land 2,

the frame is formed of a member B `provided-with an upstanding edge or ange B1 and a second ange B2 which is bent back'- ward upon .itself -so thatfthe-major portion of it is parallel to the member B. The edge A1 of the screen A is gripped and held taut between the portions B and B2. By means of this construction the effective screen 'surface' entends from edge to edge of the entire device. The screen is only in contact with .the frame at its extreme outer edge and a considerable gap or space is providedbetween the upper surface of the portion B and the l lower surface of the screen. Thus the de- `vice may bereadily cleaned as a brush or other instrument may be inserted between the screen and the frame. In the form illustrated in Figure 3, the members B, B? and B2 are the same as those shown and described in connection with Figure 2. As an added strengthening and gripping member, however,'the member B2 is extended by the provision of an upturned edge B3. Thus in the form shown in Figure 3 the edge lof the screen is gripped between the members B and B2 and between the two upturned portions B1 and B3. This forms a somewhat stronger devicethan that illustrated in .the preceding figure and one in which the screen 1s grip ed by the frame over a greater area. In igure 4 the frame is formed of a member C having a flange or lip C1 out- -Wardly bent with respect to the member C. Thus the members C and C1 lie substantially parallel throughout a portion of their width andthe member A1 is gripped between them. The member C is provided with an upwardly extending curved lip portion C v gripped. I Resting upon the upper surface of the member D and between -it and the screen A is a rod or other spacing member E which serves as: a means -for supporting the screen A and for holding it out of contact with the member D except at the edge Ving the rod F, being vpreferably `of the latter.

In Figure 6 the frame is formed yof a rod-like member F about which the edge A1 of the screen A is wrapped.` Surroundenerally concentric with it land serving with it to grip the edge A1 of the screen is a member` This member is preferably so ropor tioned as to be in-contact only wlth. the edge A1 of the screen A and to be out of lcontact with the undersurface of the main portion of the screen A.

In Figure 7 the rameis formed of a member H which is preferably inclined with respect to the plane of the screen A. The member H is provided with an inwardly or downwardly bent lip or flange H1 which may lie parallel with it, and-is joined to its upper edge. Theedge A1 of the screen is. gripped'between the portions H and- H1. The member H is provided with an outwardly extending flange or lip H2which serves as an additional stifening and strengthening member and 1n the form here shown .is'generally parallel with the plane of the screen A. y v

The form shownin Figure 8 is generally the same as that shown in Figure 7, except that the flange or lip Hzis omitted.

In the form shown in Figure 9, the frame is Vformed of a downwardly and inwardlyr inclined member I tothe lower edge -of which is attached an upwardly and outwardly inclined member I1. Between-the two the edge A1 of the screen A is engaged and gripped.'

It willbe realized that while I have herewith shown and described a practical operative device, nevertheless manyl changes might be made inthe size, shape, number an disposition of parts without departing from the spirit of my invention, and I wish,

therefore, that my showing. be, taken as in a sense diagrammatic. details of construction might be almost in'-4 finitely varied. -While in most of theforms shown the members-of which the frame is.

built up are unitary with the various flanges and lips formed as a part of the frame itp self, thisv obviously might be varied and any form, 'such as that shown in Figure 2- ory any other figure, might be formed of separate parts attached, and thus in the forni. shown in -Figure 2, the member B2 might vbe vseparate from the member B and the two might be bolted, .riveted `or 'otherwise fastened together so as to grip the screen and to serve the other purposes and accomplish 65.

. the `other objects of theframe.

lParticularly, the

4Where in the specification and claims I use theexpression-wlre mesh, I -wlsh this expression to be taken asl including any supporting member whichhas a relatively large portion of its surface open.- For the vsake of convenience the expression lwire mesh has been used but it 1s to be taken as including a cloth which might be made of strips rather than wires or bars or even a sheet of material having a large part of its surface cut away. This vmight be a sheet of metal with many perforations of any shape whatever, so as to provide a relatively large, open, cut-away or unobstructed proportion of the total area.`

It will be understood that the device of my invention isy not limited to use in the baking industry. A. pan of the sort described might'beused in many other in-` dustries, such, for example, as'the manufacture of breakfast foods, macaroni, candy and many others.

The use and operation of my invention are asl follows:

vIn any of the forms illustrated, my .invention is made as shown and is used to support goods for baking. Heretofore, Where pans'have `been used)` and particularly Where pans Aformed ofv screening have been used, it has been thought necessary to use arelatively'wide frame, in contact with the screen. The heating effect upon oods resting upon the metallic frame is di erent from that upon goods resting upon the screen. Thus a cocky which restsv upon the screen will have a different color from one which 'rests upon theframe.' at the edge of the pan and for many purposes such cookies j of different colors, or so-called discolored cookies, must be rejected. Also, when sagging of the screen portions develops, this sagging occurs from the edge of the frame member and if the frame is relatively wide, a cooky -or other article to be baked might rest partlyon the screen and partly von the frame member, or partially lon a por-` frame rests upon the screen sur ace and upon it alone and restsupon the screen at -a point at which it is out of contact with the frame. Thus'all ofthe goods, carried by the ,screen of my invention, are subject-to the same fconditions: of heat and di oloration is.

impossible. Any sagging whi my occur in the screen'will occurthroughoutits entire area and so any article upon the total.

working surface of the screen will have the same bottom shape as any other article and so distortion does not occur. Thus my invention avoids distortion and avoids dis-y coloration. Since the screen in all forms is separated from the frame whlch carries 1t throughout its entire working area, it is ossible to clean the entire screen and the rame readily because a brush o r other tool may be run under the screen between it and the oven and the necessary baking or other heating or cooking operation is carried out. When this operation is finished, the pans are removed and the baked or cooked goods are removed from the pans.
